A sense amplifier control circuit is provided to reduce current consumption due to overdrive at the high voltage by providing a sense amp control circuit controlling the pulse width of overdrive control signal and controlling overdrive of the sense amp. In a sense amplifier control circuit, a voltage comparing unit(20) generates a delay control signal corresponding to a divided voltage which is obtained by dividing a power voltage and outputting in response to enable signal controlling a sense amp. A pullup signal generation unit(30) an overdrive control signal in which the pulse width of the enable signal is changed by controlling an active signal according to a delay control signal and generates a pullup control signal.
